Memory card not being seen or read... Help Plz

Actually, I'm having this exact same problem and I am using the 2GB Samsung microSDHC card that came with the phone. Prior to the update, I never had any problems with the phone reading the memory card. After  the update (I'm not sure how much time passed but definitely less than two weeks), I have to take my card out and put it back in 3-5 times before I can access the Sideloaded videos. When I initially try to go to the Sideloaded videos, I get the "SD card can not be found. Please make sure that your SD card is properly inserted" message.

Like I said...I have to remove/reinsert the card multiple times before it will finally read the card. The strange thing is that I don't have to do this when I go to E-mail->Browse Files-> and select Pictures->Other images (from mem card) or Videos->TV/Video. It lists all of the files on first attempt...I can view the pictures and watch the videos without a problem, so it's obviously not an issue with the memory card.

The other night, I copied all of the files on the memory card to my hard drive, formatted the memory card (FAT32), put it in my phone, took a picture, hooked my phone back up to the computer, copied one video file over, tried to access Sideloaded videos, and got the SD card can not be found message again.

I did the policy hack on my phone after it was first posted on this forum and have not modified the permissions since then. The only thing that has been changed is the firmware update and let me just mention this...I didn't update my phone for 3 weeks after the update was released because I was worried that something like this would happen. However, I didn't see anyone on this forum reporting any problems after the update so I did it. Too bad I can't roll back...
